I still don't understand why Islamic groups have any connection to a Judeo-Christian monument....oh wait....
I would not put it past the Islamists to cause damage to their own mosque (Dome of the Rock) and then try to blame it on the Israeli's. That would really inflame things.
1. In the year 1313 BCE - The Israelites are in the desert, recently having experienced the miraculous Exodus, and are now poised to enter the Promised Land. But first they send out a reconnaissance mission, to assist in formulating a prudent battle strategy. The spies return on the eighth day of Av and report that the land is unconquerable. That night, the 9th of Av, the people cry. They insist that theyd rather go back to Egypt than be slaughtered by the Canaanites. G-d is highly displeased by this public demonstration of distrust in His power, and consequently that generation of Israelites never enters the Holy Land. Only their children have that privilege, after wandering in the desert for another 38 years.
2. The destruction of the First Temple in Jerusalem (423 BCE).
3. The destruction of the Second Temple in Jerusalem (69 CE).
4. The conquest of the city of Betar by the Romans. This brought to an end the Bar Kochba rebellion (133 CE). The city was pillaged and hundreds of thousands of Jews were slaughtered.
5. The plowing of the Temple Mount by the Romans, one year after the conquest of Betar.
And thats not all. The Jews were expelled from England in 1290 on - you guessed it - Tisha bAv.
In 1492, the Jews were expelled from Spain. King Ferdinand decreed that by the end of July, Spain should be Judenrein. They were then given two days extra, until the second of August, the 9th of Av. The expelled Jews were now susceptible to capture, murder, looting, and wild beastsboth the four-legged and two-legged varieties.
Word War I was declared on the 9th of Av in 1914. This war ultimately led to the political and economic upheavals which caused the Bolshevik revolution and the Holocaust.
Most interpretations of New Testament prophecy point to the fact that the Temple must be rebuilt. Only then, can the Anti-Christ defile it.
For this to happen, the Mosque will be destroyed. No one knows how this will occur, but it will occur.
